CAP-SPINDLE WASHER. I

Application filed July 26, 1921. Serial NO. 487,763.

To all whom it may com 061% Be it known that I, JAMES T. HEMING- cap spindles of spinning machines.

One object of the invention is to improve the-construction of devices of this character.

whereby greater efficiency is obtained, and wherein dust, and other foreign substances,

' are excluded from the bearings.

Another object is to provide a device of this character wherein the whirl of the spindle is adapted to be partly received in the device so that the whirl will rotate .rnore evenly.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanyin drawing.

In the drawing:

Figure l is an elevationvof a portion of a cap spindle showing the invention in position in connection therewith.

Figure 2 is a plan View of the improved washer removed from the spindle.

Figure 3 is an enlarged transverse sectional view through the washer, on the line 3-3 of Figure 2.v

Referring particularly to the accompanying-drawing, 10 represents the spindle rail of a spinning machine, in which is screwed the lower end of the vertical spindle 11. The usual lifting rail 12 is arranged above the spindle rail and receives the spindle loosely therethrough. On the spindle is arranged the whirl 13 which is driven by the belt or tape 14. The lower end of the whirl is reduced, as shown at 15, and it is this part of the whirl which engages with the washer to be more particularly described herein.

The washer rests on the lifting rail 12,

and includes the main shell 16 having the peripheral flange 17 on its lower end and reduced in successive steps, as shown at 18-19. The latter reduction 19 is in the form of a tube, the bore of which extends through the shell. shell. there is formed a recess 20 in which is disposed thefelt washer 21. The spindle 11 extends vertically through the washer 21 and the central bore of the shell. On the upper face of the shoulder 18 there is formed a groove 22, which receives the circular series of bearing balls 23. Fitted frictionally on the portion 19 is the depending flange of the cap 24:, the lower edge of said,

cap resting on the shoulder 10 of the shell. The upper portion of the cap extends horizontally toward the center of the bore of the shell, and sufficiently far to retain the balls 23 within the shell. As the whirl 13 is rotated its lower reduced end 15 runs smoothly on the upper portions of the balls 23, the said reduced portionfitting snugly within thecircular opening within the horizontal portionof the cap 24. The positioning ofthe portion 15, within the shell, serves to exclude dust'from the bearings, while lubricant can pass upwardly from th f lt washer 21. I What is claimed is:

A device of the class described compris- In the bottom of the steps, the vertical face of the ball supporting I step being threaded, and a cap screwed onto the said threaded portion of the step in such position that the flange of the cap serves to prevent outward movement of the,

balls, the body having'a vertical flange above the ball carrying step serving to prevent inward movement of the balls, and the upper wall of the cap being formed with a central opening exposing portions of the balls for engagement by and supporting engagement with-a spindle whirl.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
